TAK-659 HCl

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 206169

CAS#: 1312691-41-0 (2HCl)

Description: TAK-659 is an inhibitor of spleen tyrosine kinase (syk), with potential anti-inflammatory, immunomodulating, and antineoplastic activities. Spleen tyrosine kinase inhibitor TAK-659 may inhibit the activity of syk, which abrogates downstream B-cell receptor (BCR) signaling and leads to an inhibition of B-cell activation, chemotaxis, adhesion and proliferation. Note: TAK-659 free base is less stable. This product is supplied as dihydrochloride form.
